The mean pLDDT of this model is 84.9 (confident overall). pLDDT is AlphaFold's per-residue confidence score from 0 to 100. In MolViewer, choose the B-factor color scheme to color the model by pLDDT, because AlphaFold stores it in the B-factor column.
| pLDDT band | Meaning | Share of residues |
|---|---|---|
| Above 90 | Very high: backbone and side chains are usually accurate | 45% |
| 70 to 90 | Confident: backbone generally right | 43% |
| 50 to 70 | Low: treat with caution | 8% |
| Below 50 | Very low: often disordered regions | 3% |
What pLDDT means and how to read it
Integrin ITGAL/ITGB2 is a receptor for ICAM1, ICAM2, ICAM3 and ICAM4. Integrin ITGAL/ITGB2 is also a receptor for the secreted form of ubiquitin-like protein ISG15; the interaction is mediated by ITGAL (By similarity). Integrins ITGAM/ITGB2 and ITGAX/ITGB2 are receptors for the iC3b fragment of the third complement component and for fibrinogen. Integrin ITGAX/ITGB2 recognizes the sequence G-P-R in fibrinogen alpha-chain. Integrin ITGAM/ITGB2 recognizes P1 and P2 peptides of fibrinogen gamma chain. Integrin ITGAM/ITGB2 is also a receptor for factor X. Integrin ITGAD/ITGB2 is a receptor for ICAM3 and VCAM1. Contributes to natural killer cell cytotoxicity (By similarity). Involved in…
Heterodimer of an alpha and a beta subunit. The ITGB2 beta subunit associates with the ITGAL, ITGAM, ITGAX or ITGAD alpha subunits. Found in a complex with CD177 and ITGAM/CD11b (By similarity). Interacts with FGR (PubMed:19903482). Interacts with COPS5 and RANBP9 (By similarity). Interacts with FLNA (via filamin repeats 4, 9, 12, 17, 19, 21, and 23) (By similarity). Interacts with THBD (By…
